Once your geometry is set-up in terms of materials, then it’s time to look at lighting. This means that material definitions are interchangeable with any other applications that support it - which includes all of the other Iray applications as well as some third party rendered, such as Vray (which added support for MDL recently). It’s also worth noting that Iray uses the MDL (Material Definition Language) to define its materials. It was a nice little workflow to add 8 different plastic variants to the scene, edit the colour parameters (which we had already written out), then use Rhino’s ‘Select by Colour’ tools to quickly apply them to all of the appropriate geometry in one go. Grab the ones you want, add them to this shortlist and they’re there.Īnother benefit of this approach is if you have a model and have all of the material defi nitions you need, it’s relatively quick to add in the materials you want (or the closest approximation) then rip through the edit dialogs to adapt them to your specific requirements.Īs an example, the model we’re showing here had 8 different materials in it. To overcome this, you can add materials to that specific scene, without having to assign them to geometry. You have hundreds of materials, so this is a little unwieldy. It’s worth a few notes on how the library works.
To apply the materials, you use the standard Rhino selection tools to select the geometry, find the materials and away you go. They’re categorised in a sensible way, so this doesn’t require too much learning. This pops up a tidy dialog that gives you access to all of the materials and their settings. To get at these, you hit the ‘materials’ command from the Iray toolbar. The good news is that the system is supplied with a pretty extensive set of materials that cover both product design and architecture. The first step is to replace any material definitions with those from the preinstalled Iray libraries. Iray is a progressive renderer, so your viewport shows you result of your edits quickly - there’s no need to do a test render. This means that when you load your model, switch your viewport to Iray, then you’ll get a nicely rendered image of a white model. The first thing to know is that Iray uses a different set of materials compared to the standard Rhino definitions. We’re going to follow the process for setting up a render scene and then explore the various options and parameters that let you dial things in and get you a good usable result. Other than that, it’s pretty much a case of loading up your model and cracking on.
If you’re familiar with Rhino, then you’re 80% of the way there with Iray for Rhino.Īll that changes is that you have a number of new toolbars that gives you access to the various settings, the materials library and light set-up.
